Locate the available departures for Salt Lake City Airport (KSLC). On AirNav, the list looks like this:
You’ll notice a mix of conventional departures like the “Salt Lake #” and RNAV departures like the ARCHZ#. The RNAV departures are denoted by the "(RNAV)" symbol. First, open the ARCHZ# departure:
As you can see, this SID requires RNAV capability and is only available for turbojet aircraft. Notice also that the routing is a little different than what we saw out of KJAC. This is a "radar vectored" departure, meaning that you need to receive direction from ATC before joining the route. (By comparison, at KJAC, we were able to fly directly from the runway to join the SID.) Furthermore, notice how the departure is comprised almost entirely of waypoints that are only accessible via the GPS; there is no VOR radial that could be flown to navigate along the procedure.
You’ll also notice that this SID only provides departure information from Runways 34L/34R/35 and Runways 14/32/16L/16R/17 are marked as not authorized ("NA"). That’s because departures from the south runways are to use the ZIONZ# departure instead:
Just like when we were arriving at KSLC in the previous flight, use the planned departure runway to determine which SID to use. If you plan to depart from Runway 16R, you would use the ZIONZ# departure. For this flight, we’ll assume the wind favors a northbound departure (from Runway 34L, in this example) and so we’ll use the ARCHZ# departure.
Like at KJAC, the first step is to look carefully at the SID. The "departure route description" explains that, after departing from Runway 34L, fly a heading as assigned by ATC and wait for radar vectors to the SCANT waypoint. This means we can’t turn direct to SCANT until ATC instructs us to do so. Here, we also have a published top altitude—the maximum altitude you can climb to until given further instruction—is to be "assigned by ATC" in your IFR clearance. Other SIDs will include a specific top altitude of FL230. If ATC doesn’t provide any altitude information in the IFR clearance (or simply says "climb via SID"), we’ll know that FL230 is the highest we can climb to until given further instructions. If flying without ATC, set FL230 as the initial top altitude—the maximum altitude you can climb to until given further instruction—is to be "assigned by ATC" in your IFR clearance. Other SIDs will include a specific top altitude.
Now that you have an idea of the initial departure instructions, program the SID into the aircraft. This often involves selecting the SID, departure runway, and transition. On this SID, the transitions are KROST, MLF, and WININ; we’re going to use the MLF transition since it’s most along the direct route to KBCE. Once programmed, review each waypoint in your GPS or FMS to make sure that it matches the published chart. If your aircraft has VNAV capability, also check that the altitude restrictions (SCANT at 10,000 ft. or above, ARCHZ at 13,000 ft. or above, and TRILA at FL190 or above) are incorporated.
Once your GPS/FMS is programmed with the ARCHZ# departure from Runway 34L and you have confirmed “SCANT” as your first waypoint, you’re ready to start programming the enroute portion of Learning Flight 3.
